pictctrl picture-based controls pictctrl facilitates the creation of graphically appealing (or unappealing) controls in Max. It uses images stored in an external file for its appearance.pictctrl implements three kinds of controls: buttons, toggles, and dials. Toggles are like buttons, but "stick" in one state or the other. Dials are controls that have more than two states, such as knobs and rotary switches.
